Happy birthday, Mr. President...
Obama turns 51 on Saturday, when he'll celebrate in Chicago with a backyard party. Two supporters will be conveying their birthday wishes face to face, after the Obama campaign offered invitations to the president's party as an incentive to make a donation.
Barack Obama was born Aug. 4, 1961 at Kapiʻolani Maternity & Gynecological Hospital in Honoloulou, Hawaii.
